THE WORK OF THE DIGESTIVE GLANDS. 



condition. It appears to me that this fact strengthens our previous 

 supposition, that in the digestion of bread a large accumulation of hydro- 

 chloric acid has to be avoided. 



In any case, the relationship just discussed between the gastric and 

 pancreatic secretions bears interesting testimony to the complexity

and beauty of the digestive mechanism. Obviously a rich field of work 

 lies here, full of important and, as yet, unsolved problems. 



The work of the pancreas, like that of the gastric glands, is specialised 

 both as regards the quantity and property of its juice, and the rate of 

 progress which the secretion takes for the different classes of food. 

 This is represented in the accompanying figures and curves (Figs. 9 

 and 10) taken from the work of Dr. Walther.
